Item Avaliação dos testes de resistência em luvas de látex utilizadas em procedimentos odontológicos.(Universidade Brasil, 2024) Beserra, Leidiana Viana; Costa, Mardoqueu Martins daIn clinical practice, professional activities are subject to various occupational risks, among which biological risks stand out for involving pathogens such as bacteria, fungi, protozoa, viruses, and parasites. These agents can invade the body via cutaneous, digestive, and/or respiratory routes, manifesting according to the individual’s immune response. To ensure safe practice and minimize potential contamination, biosafety measures include adopting rigorous protocols and using Personal Protective Equipment such as latex gloves. However, these products can present variations in quality and mechanical resistance among different brands, which compromises the safety of professionals and patients. Therefore, this study aimed to evaluate the quality of latex procedure gloves used in dental clinics, focusing on their mechanical resistance and impermeability. Four brands were analyzed through visual inspection and integrity testing, impermeability testing, and tensile strength tests, which made it possible to determine the maximum force, maximum tension, and elongation before rupture. Dimensional tests revealed no significant difference in glove length among the manufacturers, and width remained consistent, with no notable differences between brands A and D. In the impermeability test, deformation was observed in all brands, with gloves A and B showing no tears, while gloves C had multiple holes and gloves D exhibited leakage near the cuff. Regarding tensile strength, a good stretching capacity before rupture was found, with a maximum force ranging from 12.16 N to 17.94 N (mean of 14.86±2.45 N) and a maximum tension ranging from 38.30 MPa to 56.52 MPa (mean of 46.81±7.76 MPa). Elongation values ranged from 907.04% to 1137.21%, with a mean of 1037.32±89.20%, indicating differences in performance among the analyzed brands and underscoring the importance of carefully selecting products with proven quality control. It is concluded that significant differences exist in terms of impermeability and mechanical resistance of latex gloves, emphasizing the need for a thorough evaluation of these materials to ensure the safety of professionals and patients, thereby helping reduce biological risks in clinical practice and serving as a basis for future research on the quality of this personal protective equipment.
